在依赖地理上分散的可再生原料和波动的能源发电的未来世界经济中，电化学获取与工业相关的化学品提出了一个关键概念。在这里，我们展示了从生物平台化学物质琥珀酸合成工业上相关的己二酸酯和丙烯酸酯单体。通过Kolbe和非Kolbe电解法，己二酸二乙酯和丙烯酸乙酯的选择性分别达到74%和58%。我们发现，RuO2涂层的钛电极是大量铂电极的极佳替代品，显著降低了贵金属成本，并通过在有机体系中用钛取代高达75%的Ru，进一步降低了贵金属含量。经济的碳电极通过抑制二聚反应来瞄准丙烯酸酯单体。应用来自真实风车能量分布的瞬变条件，我们证实了一种高效的动态操作，为由高效的瞬变电催化过程驱动的可持续化学工业铺平了道路。
In a future world economy relying on geographically decentralized renewable feedstocks and fluctuating energy generation, an electrochemical access to industrially relevant chemicals presents a key concept. Herein, we demonstrate the synthesis of industrially relevant adipate and acrylate monomers from the biogenic platform chemical succinic acid. Adipic acid diethyl ester and ethyl acrylate are available with up to 74% and 58% selectivity by Kolbe and non-Kolbe electrolysis. We show RuO2-coated titanium electrodes are an excellent replacement for bulk platinum electrodes significantly reducing noble metal costs, and reduce the noble metal content further by replacing up to 75% of the ruthenium with titanium in organic systems. Economical carbon electrodes target the acrylate monomer by suppressing dimerization. Applying transient conditions derived from a real windmill energy profile, we confirmed an efficient dynamic operation paving the way for a sustainable chemical industry driven by efficient transient electrocatalytic processes.
